ABOUT ME I'm a full time freelance software developer and consultant, highly experienced in designing, developing and managing web, mobile and desktop applications of all sizes. I've been developing software commercially since 1998, and a hobby programmer since my childhood. I currently own and operate Brava Software Solutions, a software consulting and development agency currently based in Alicante, Spain. Previous clients and work experience include Quill Meetings, DHL, Securicor Omega Express, Capscan, Monsternett AS, The Restaurant Zone LLC, Sunfly, Dooster, Claims4Free and more. I'm a native English speaker, originally from London. WHY SHOULD YOU HIRE ME? Let's be honest .. you've probably seen my bid and thought, "Wow, that's a little higher than some of the others, what makes this guy worth it?" Well .. hire me and I'm sure you'll very quickly see why. Not only do you get a highly motivated and passionate software developer with decades of experience focused on your project, depending on your needs, you can also access to the highly talented team of engineers and dedicated project manager that my agency can provide. No middle men or answering services, you get to talk directly to the people working on your code. I also strive to offer a flexibility towards my clients needs that is hard to find in this industry and will happily adapt working hours to suit your needs, whether you need just a few hours every now and then, or a huge dedicated burst to meet a deadline, you'll find you can count on me to deliver. Not only do I pride myself on producing clean, robust test-driven and fully linted code, but because it's second nature to me I can also do this fast and efficiently. I'm confident that you'll not only receive outstanding results, but as my many repeat clients will agree, you'll end up getting far more value than the cheaper competitors. I'm also very picky about the projects I choose to bid on, only pursuing ones that I feel will be truly engaging over the long term. By approaching work this way, you'll find that I throw myself into my work like nobody else. You'll find that you'll get not just a developer, but an individual who's genuinely passionate about what he does and someone you can rely on to handle every technical aspect of your project from start to finish and beyond if needed. EXPERIENCE AND QUALIFICATIONS I am widely experienced in several areas of software development having undertaken a large range of jobs over the years from traditional desktop applications to modern cloud and mobile based technologies.

In addition to Linux, I also have significant development experience on Windows and many Windows specific toolchains such as Visual Studio as well as moderate experience with both desktop and mobile application development on Mac OS. I am happy to consider projects of all shapes and sizes, and pride myself on offering a fast, friendly and reliable service, and am always happy to push the extra mile for you. Programming has been my passion from an early age and I take great pride in the work I provide, always aiming to perceive the long term goals of any project and avoiding shortcuts in order to build the best product possible.
